90PR2KLFTB

Application Field

90PR2KLFTB is widely used in the industrial, home automation, commercial and consumer electronics applications. It is a type of device for manual adjustment of a specific parameter in an electronic circuit. 90PR2KLFTB can be used as a voltage divider, or in place of a variable resistor to adjust current flow, or for dependent voltage adjustments. For instance, it can be used for controlling the LCD display brightness or audio volume, or to adjust the speed of a motor and other related applications.

Working Principle

The basic structure of 90PR2KLFTB is formed by two resistors connected in series, the left part and right part connected with the rotating plate of the control knob to deliver a variable range of resistance.The center pin of the device works as a common pin between the two parts of the resistor. When the knob turns, the resistance of the left part and right part will change and the resistance between the center pin and the two external connections will adjust accordingly.

90PR2KLFTB can be connected in the circuit as a voltage divider or to control a current. It is also used to adjust the output of an amplifier or the frequency of an oscillator. This yields a range of adjustment from one end of the range to the other.

Conclusion

90PR2KLFTB is a type of adjustable trimmer potentiometer devise widely used in a variety of applications such as lighting control, motor speed adjustment and voltage adjustment. It can be connected in a circuit as a voltage divider or used to control a current, and is adjustable from one end of the range to the other.
